Title: Power converting circuit
Inventor: HANAKA IKUTARO
IPC: H02M5/25
Filed: 1987-12-03
Abstract: PURPOSE:To obtain a power converting circuit with a small power loss by using an auto-transformer having a necessary minimum capacity as an output transformer. CONSTITUTION:As to a three-phase load, the required capacity per phase of a three phase auto-transformer Tb is expressed by the equation I. When a secondary side phase voltage V2P is a little larger than a primary side phase voltage V1P, V2P V1P, that is, the required capacity W1P may be sufficiently smaller than the product of the secondary side phase voltage V2P and a three-phase balanced load phase circuit I3. As to a single-phase load, on the other hand, there is a small unbalance in load capacities between respective phases, because load equipment groups are distributed and connected between respective phases. Said auto-transformer Tb works as a reactor having a neutral-point for the load and each phase capacity W1l is expressed by the equation II. Therefore, the total capacity W1 per phase of the auto-transformer Tb is expressed by the equation III and the capacity per phase of the auto-transformer Tb may be a little larger than the required capacity.

Title: Screw compressor
Inventor: TSUBOI NOBORU
IPC: F04C18/16
Filed: 1990-11-08
Abstract: PURPOSE:To enhance sound suppressing performance as well as to make a device smaller in size by forming a casing with both a swelling space continuously connected to a discharge port and a small cross sectional flow passage which changes the direction of discharge gas flow into a L-shape so that discharge gas thereby flows out. CONSTITUTION:A swelling space 5 is formed in the transverse direction of a discharge port 4 while being continuously connected to the discharge port 4 of a casing 3 which rotatably houses a pair of mutually meshed male and female screw rotors 1 and 2 arranged in parallel in the longitudinal direction, and a small cross sectional flow passage 6 is concurrently formed in the same casing 3 housing the screw rotors 1 and 2 along the wall section of a rotor chamber housing the screw rotors 1 and 2 while being continued from the swelling space 5. This thereby allows compressed gas to be discharged out of the discharge port 4 to the voluminously large swelling space 5 so as to be hit against the wall section of the space, and also allows it to be changed in direction so as to be led into the small cross sectional flow passage 6 thereafter, thereby weakening the propagation of sound, so that noise is therefore lowered. In addition, the whole of a device can thereby be made smaller in size than any compressor furnished with a sound suppressing structure separately.
